11298859 · 2022-04-12 · ·

A method for injection molding comprises forming a set of first articles in a mold of an injection molding machine and forming a set of second articles in the mold of the injection molding machine. The method includes transferring the set of first articles from the mold to a first set of first receivers of a tooling plate, and then moving the first set of first receivers to align with the set of second articles. Thereafter the set of second articles is transferred from the mold toward the first set of first receivers and into assembled condition with the set of first articles held in the first set of first receivers.

INJECTOR

In a configuration in which a guide member that guides an intermediate member to be slidably movable is provided on an upper surface of side support plates, a bending buffer portion is provided in a first region of the side support plates which is located more outward than a part of the side support plates on which the guide member is provided. The bending buffer portion is configured to be bent and deformed easier than a second region of the side support plates in which the guide member is provided.

An injection molding machine device includes at least two guide rods. One end of each guide rod is fixed to a rack, and the other end of each guide rod is fixed to a fixed base body. A movable base body is provided opposite to the fixed base body. The movable base body slides along the guide rods relative to the fixed base body. At least one correction mechanism is located between the movable base body and the guide rail to adjust a movement of the movable base body in a vertical direction. A predetermined clearance value and/or a predetermined contact force value exist between the components. At least one sensor is electrically connected to a controller. The controller correspondingly controls the correction mechanism by determining whether corresponding detecting values of the sensor match with the predetermined clearance values and/or the predetermined contact force values.

A system for forming injection molded articles includes a turret, a first mold unit, and a second mold unit. In an embodiment, the turret includes a plurality of core plates and each core plate includes a plurality of core pins. The first mold unit may be configured to form an inner injection molded layer, and the second mold unit may be configured to form an outer injection molded layer over the inner injection molded layer. In an embodiment, the first mold unit and the second mold unit are configured to mold at the same time, and to provide opposing clamping forces. Processes involving over-molded articles are also disclosed.

PLASTICIZING UNIT

A plasticizing unit is provided for an injection unit of an injection moulding machine with a support element arranged beneath the cylinder and connected therewith. To simplify adjusting of the nozzle centre, a fixing element surrounds the end of the support element facing away from the cylinder such that a distance is present between the fixing element and the support element. Several adjusting elements are provided, to produce a force-fitting and/or form-fitting connection between the fixing element and the support element to adjust the position of the support element relative to the fixing element in a plane orthogonally to the cylinder axis. The plasticizing unit can be clamped in and out with its fixing element in a clamping- and positioning system connected with the machine bed. On changeover of the plasticizing unit, an adjusting of the nozzle centre, which has been carried out once, is retained.

Movable platen, opening/closing apparatus and molding apparatus

A movable platen according to the present invention includes: a mold clamping platen 42 having a projecting portion 62 in a mold closing direction-side surface; a mold mounting platen 44 mounted to the projecting portion 62 of the mold clamping platen 42; and a guide mechanism 50 fixed to the mold clamping platen 42 and supporting the mold mounting platen 44. Only the mold clamping platen 42 is fixed to the guide mechanism 50, while the mold mounting platen 44 is not fixed but placed on platen surface support portions 52.

INJECTION-COMPRESSION MOLDING DEVICE

An injection-compression molding device (1), wherein the rod (3) and the core (5) are connected to each other by means of a joint (20) which allows to have a rigid connection in some steps of an injection-compression molding process, and an articulated connection during the compression step of the injection-compression molding process.

METHOD FOR MOVING A MOVABLE PLATEN

A method for moving a movable mold mounting plate of a molding machine, wherein the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other and wherein a drive mechanism for moving the movable mold mounting plate is provided, wherein molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state and wherein a temporally changeable tilting movement of the mold mounting plates relative to each other occurs by the movement of the movable mold mounting plate, wherein the movable mold mounting plate is moved by the drive mechanism and/or the stationary mold mounting plate is moved by an injection device in such a way that when reaching a predeterminable distance of the mold mounting plates relative to each other a parameter representing the tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value, preferably equal to zero.
